Thanks Merelcoin :

- fix the issue you have with zapwallettxes (like knightdk said)
I opened the terminal and did : open /Applications/bitcoin-qt.app --args zapwallettxes
It opened but nothing changed

- fix the issue you have with abandontransaction (like knightdk said) :
I did abandontransaction 1d150ad498c23524dcb60198d41676f3b44060fc37ac2d7e76f8625be4e5562c
But Transaction not eligible for abandonment (code -5) came

- create a double-spend/RBF
I can't since my balance is at 0
